W y I I yw Patented May 13, 1930 UNITED STATES PATENT OFFICE" ROBERT HUDSON WAGER, or annsnig' CITY, NEW JERSEY AIR REGISTER Application filed August 16, 1928. Serial No. 300,046.

The invention relates to air registers and more particularly to those designed for ventilating purposes, for instance in the ceilings of staterooms, hotel and office rooms, etc.

It is one aim of the invention to provide an improved register of simple and inexpensive construction which maybe easily adjusted to admit the desired amount of air or to stop such admission, and will be effectively held against accidental movement from its. adjusted position.

Another obj eet is to provide an air deflector mounted in a novel manner for preventing direct inrush of air, with consequent danger of disarranging ladiesapparel and'hair.

Yet another aim is to provide the air defiector with a hub" of such form as to encase a spring which is instrumental in holding the register in adjusted position.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being ac-- complished by reference to the accompanying drawings.

Fig. 1 is a side elevation showing the register secured to a ceiling through which an air admission pipe extends.

Fig. 2 is a vertical sectional view through the parts shown in Fig. 1.

Fig. 3 is a top plan view partly in horizontal section.

Fig. 4 is a horizontal sectional view on line 41 of Fig. 2.

Fig. 5 is a detail vertical section on line 55 of Fig. 3, parts being omitted.

Fig. 6 is a detail vertical sectional view on the correspondingly numbered line of Fig. 3;

Fig. 7 is a side elevation of the shaft for turning the movable disk which co-acts with a stationary cliskin controlling the admission of air.

The drawings above briefly described illustrate the preferred form of construction and while this construction will be herein specifically explained, it is to be understood that within the scope of the invention as claimed, variations may be made.

The device embodies a stationary disk 10 having a central shaft-receiving opening 11 and a plurality of air-conducting openings 12 spaced around said opening. A continuous wall 13 is integral with the eripheral portion of the disk 10 and at its ree edge is provided with an outstanding attaching flange 14: adapted to be secured to a ceiling 15 or other support, by bolts 16 or any other desired fasteners. In the present showing, an air admission pipe 17 passes through an opening in the ceiling or other support 15 and is snugly received within the wall .13.

A rotatable disk 18 liesagainst the disk 10, within the confines the wall 13, said rotatable disk 18 being formed with a central opening 19 and with a plurality of air-conducting openings 20 spaced around said opening 19, for communication when desired with the openings 12. The relation of openings 1220 is such that upon turning of the disk 18 to one position, no passage of air can take place through said openings. Disk 18 is provided with a peripheral, limit lug 21 which is operable between a pair of circumferentially spaced lugs 22 formed on'the inner side of the wall 13. When lug 21 is in contact with one of the lugs 22, the register is open to the maximum and whensaid' lug 21' contacts with the other of the lugs 22, said register is fully closed. In intermediary adjustments, the register will of course admit the desired quantity of air. j 7

An operating shaft 23 is provided for the disk 18, one end of this shaft being passed through the opening 19. By means of a nut 24, the disk 18 is clamped against a shoulder 25 on the shaft 23, and relative rotation of shaft and disk is prevented by an appropriate key 26. Shaft 23 passes through the opening 11 and projects outwardly beyond the disk 10, said'shaft being provided near its outer end, with an outwardly facingshoulder 27. A hand wheel or other handle 28 is secured upon the outer end of shaft 23 and is locked thereon by a lock-nut 29, and said handle and shoulder are instrumental in securing a substantially conical air deflector 30 to the shaft.

The deflector 30 is provided with a central hub 31 having a longitudinalsoeket 32 opening through one of its ends, and an opening 33 extending to its other end from the socket bottom 34. The outer end portion of the shaft 23 passes through the opening 33, the socket bottom 34 abuts the shoulder 27 and the handle 28 abuts the outer end of the hub 31, thereby tightly securing the latter to the shaft.

A coiled compression spring 35, surrounds the shaft 23 within the socket- 32, the ends of said spring abutting the stationary disk 10 and the socket bottom 34 respectively. Thus, the spring acts longitudinally upon the shaft 23 and re-acts upon the stationary disk 10, thereby holding the rotatable disk in tight frictional contact with said stationary disk 10, so that said rotatable disk is effectively held in any position to which it may be adjusted. l/Vhen disk 18 is being held in one of its adjusted positions, a slight space 36, exists between the disk 10 and the hub 31. This permits sufficient inward movement of the shaft 23, incident to turning the handle 28, to relieve the friction between the disks 1018, permitting easy turning of the latter.

It will be seen from the foregoing that I have provided a rather simple and inexpensive, yet an efiicient and desirable register for ventilating purposes. Any desired amount of air may be admitted or the admission of air may be entirely checked, as occasion may demand. WVhen air is being admitted, the deflector 30 prevents the discharge of a direct blast into the room from the pipe 17 and hence there is no danger of disarranging the hair or the apparel of its occupants. The central hub 31 of this deflector 3O acts not only as part of a unique arrangement for securing the deflector to the shaft 23, but serves also as encasing means for the spring 35 and hence assists materially in providing a compact structure having an exceptionally good appearance. In case the ventilator should be hard to open or close from any cause so that it could not be readily turned by the handle 28, the periphery of the air deflector 30 may be grasped with one or both hands so that said deflector may be used as turning means for the shaft 23. As said periphery of deflector 30 is a greater distance from the shaft than the periphery of the handle 28, more turning leverage may be exerted on the shaft and consequently it may be readily rotated.

The exact details disclosedhave in actual practice proven to be advantageous to the maximum from numerous standpoints. These details are therefore preferably followed as above stated. However, attention is again invited to the fact that within the scope of the invention as claimed, variations may be made. a
